Synergistic Vibrational Suppression and Aggregation Control via a Rigid Dimeric Acceptor for 21.13% Organic Solar Cells.
The efficiency bottleneck of organic solar cells (OSCs) is predominantly hindered by severe non-radiative energy loss (ΔE3), which primarily originates from strong electron-phonon coupling and detrimental charge recombination into darker state traps. Herein, we designed and synthesized a highly rigid and polarized dime...
